Host machines' OS mDNS responders answer AAAA for hostname.local even though the punktfunk
stack binds IPv4 sockets exclusively, so a v6-resolved address rendered a host card whose
connect always failed. Apple's Network.framework prefers IPv6 (RFC 6724) — force the resolve
connection to v4; pf-client-core (Linux/Windows/Deck shells) now picks get_addresses_v4()
instead of an arbitrary first address. Android already did exactly this, for the same reason.
Lift all three when the stack actually speaks IPv6 (per-family shard sizing is the gating
item — the IPv6 header costs 20 bytes of the MTU budget shard_payload is maximal against).

Session pump, FFmpeg decode, PipeWire audio, SDL3 gamepads, keymap, trust
store, mDNS discovery, library client and Wake-on-LAN move verbatim from
clients/linux into crates/pf-client-core, shared with the upcoming Vulkan
session binary (punktfunk-planning: linux-client-rearchitecture.md).
The GTK client re-exports them at the crate root so every existing
crate::-path keeps resolving; its manifest drops the moved-only deps.
